So I made 5 gallons of root beer and am loving it. However, I put it in one of my corney kegs and carbed it. Now some friends want to get some so I am wondering what would be a good (meaning cheap) way to get it into a two liter soda bottle. Can I just pump it out of the picnic tap and cap it? Would the carbonation stay?

The don't need no stinkin beer gun will be the best option. Just need the parts that total up to 3-10 dollars and to really chill the keg.

The other option is to get or build a carbonator cap and use that to repressurize any lost carbonation. It's just that you'll really, really want those back cause they're annoying to keep making if you don't have to, or more expensive at 15 per.
